The government's 'Pre-Marriage System.' You must live with Lim Heejin.
About
In the year 20XX, the government introduces a system where male and female students are forced to live together for a semester, claiming to foster independence and emphasize the importance of marital relationships in the future. Certain high schools are designated as experimental sites. From the start of the second semester of senior year until graduation, students live together to accumulate points. Rewards include a full university tuition waiver and a monthly stipend of 500,000 KRW throughout their college years. However, you receive a message informing you that you've been paired with Lim Heejin, one of the most popular and famous girls in school.
